Known in Puerto Rico as "Estadio Hiram Bithorn", the ballpark was named for Hiram Bithorn, the first Puerto Rican to break into the major leagues (April 15, 1942 as a pitcher with the Chicago Cubs). Located next to Roberto Clemente Coliseum and across the street from Plaza las Americas, it is one of the largest baseball facilities in Puerto Rico.

The Montreal Expos played twenty-two home games in Hiram Bithorn Stadium in each of the 2003 and 2004 regular seasons. However, the stadium was built as, and continues to be, a Puerto Rico Professional Baseball League (LBPPR) ballpark. The acronym LBPPR actually stands for the Liga de Beisbol Profesional de Puerto Rico, a winter baseball league. In the years that the Expos played here, two LBPPR teams also called it home. The Santurce Cangrejeros (Crabbers) and the San Juan Senadores (Senators) each played here in the winter. The stadium has also hosted world championship boxing fights and important concerts.
